The OperatorPresenceControllever(A, Figure3-1) regulatesthe operationofthe rearwheelbrakeandthe separateBladeDriveControl. Alwaysengagethiscontrol beforeengagingthe separatebladedrive or wheeldrivecontrols.Alwaysdisengagethis control beforestarting theengine.To engagethe OperatorPresenceControl,pressand holdthe leveragainstthe handlebargrip. Doingso releasesthe brakeon therearwheels,allowingthe wheelsto turn.Theengagedpositionalsopermits theseparateBladeDriveControlto lock in its engagedposition(allowsthe mowerbladesto turn).

Releasinghe lever (disengagedposition) appliesthe rearwheelbrakeandquickly stops thewheels.Releasing

the leverwill also disengagethe BladeDriveControl,which will applya brakethat stops the bladeswithinthree (3)seconds.Blade Drive Control

Usethis lever(B,Figure3-1) to en-gagedriveto themower blades.To engagethe blades,first engagetheOperatorPresenceControl (A, Figure3-1). Then,push thespring-loadedBladeDriveControl lever (B)forward until itstays in theengagedposition.

To stop the blades,releasetheOperatorPresenceControl (A). Doingsowill disengagethe BladeDriveControl(B) andautomaticallyapply the brakethat stops the blades.

Alwaysdisengagethe BladeDriveControlbeforestarting theengine. Thishelpsto ensurethatthe bladeswill notstart turning whenthe enginestarts.

Operation

Before operating mower, be sure toread all safety, controlsand operatinginstructions in this Manual and ondecalslocatedonmachine.Severe personal injury or propertydamage couldresult if this instructionis notfollowed.

BEFOREOPERATINGMOWER1. Pre-OperaUon ChecklistWith the sparkplug wire disconnectedfrom thespark plug,performthe follow-ing checksandservicesbeforeeachuse:1. ReviewSection1: "Safety"andSection

3, "FeaturesandControls" in this man-ual. Readthe separateEngineOwner'sManualprovidedwith the unit.

2.Checkunit for looseor missing hard-ware.Tightenor replaceasneeded.

3. With the unit on levelground,checktheengineoil levelaccordingto theinstructionsin the EngineOwner'sManual. Theoil levelshould beat theFULLmarkonthe dipstick or up tothetop ofthe oil fill holeon engineswith-out a dipstick.

4. Checkall leversfor freedomof move-ment. Readjustor repairasneededbeforestarting engine.

5. Checkthat all guards andshieldsarein placeand properlysecured.

6. Inspectthe areato mowedandre-moveanydebris which could bepickedup andthrown bythe mowerblades.

7. Checkthat the mulchercoveris prop-erly installedin the dischargeopening(seeinstructionsin this Section).Removethe mulchercoverto usetheside-dischargemowingfeature.

8. Onelectric start models,checkthatall wiring connectionsare cleanandtight.

9. Checktheair pressurein thereartires (15-20 PSI). Keeptires inflatedequally.

GASOLINESHIGHLYFLAMMABLEANDITS VAPORSAREEXPLOSIVE.To helppreventseverepersonalinjuryor prop-ertydamage: Follow gasoline safety rules inSection1: "Safety" of this Manualandin the separate Engine Owner'sManual. Neverremovethe gasolinefill caporadd fuel when indoorsor when engineis runningor still hot.Allow enginetocoolat least three (3) minutes beforerefueling. Keep smokingmaterials, sparks orflamesfar awayfromfuel tankandfuelcontainer. Store gasoline in an approvedfuelcontainerandin a well-ventilatedarea.Storeit safely outof the reachof chil-dren. Do notstore gasolinewhere va-porscan reachan opensparkor flameor where ignitionsourcesare present(suchas hot water or space heaters,furnaces,clothesdryers, stoves,elec-tric motors,etc.). Fill tankto 1/2"belowbottomof fillerneckto allowfor fuel expansion.Wipeup spilled gasoline immediately andmovemowerawayfromgasolinefumesbefore starting engine. Securely re-place caps on fuel tank and fuelcontainer.

10.Removethefuelcap andcheckthelevelof gasolineaccordingto the in-structions in the EngineOwner'sManual.Cleanaroundfuel fill areabefore removingfuelcap. Donotcheckfuel levelor addfuelwhile in-doors or if engineis running or hot.Allow engineto coolfor three (3)minutes. Fillthe tankwith fresh,

clean unleadedgasolinewith a mini-mum octanerating of 77.

To avoid personalinjury, do notadjustcuttingheightwhile wheels or bladesare turning. Release all handlebarcontrolsandwait for all motionto stopbeforeadjustingcuttingheight.

1. Releaseall controls beforeadjustingthecutting height.2. Adjustthe cutting heightfrom 1to 4inchesby rotatingthe CuttingHeightControllever (Figure3-4) either clock-wiseto raisethe heightor counterclock-wiseto lowerthe height. Notethat ac-tual cutting heightswill vary accordingto grassandsoil conditions. A decalandpointer on the right sideof the mowerdeckindicatesthe height setting.3. In heavyor tall grass,it is usuallybetterto makethe first cut at a highersetting andthen makeasecondcut atthedesiredheight. In roughterrain, ahighersetting is recommendedas it willminimizethe chancesof the bladestrik-ing theground or hidden obstructions.
